Synopsis

Apache 2.4.x < 2.4.55 Multiple Vulnerabilities

Description

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.55. It is, therefore, affected by multiple vulnerabilities:

 - A crafted If: request header can cause a memory read, or write of a single zero byte, in a pool heap memory location beyond the header value sent. This could cause the process to crash. (CVE-2006-20001)

 - HTTP Request Smuggling vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. (CVE-2022-36760)

 - A malicious backend can cause the response headers to be truncated early, resulting in some headers being incorporated into the response body. If the later headers have any security purpose, they will not be interpreted by the client. (CVE-2022-26377)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache version 2.4.55 or later.
